Bottlescontaining pompressed air for instantaneously inflating the inner tubes of bicycles are already known. The devices used for this purposeup to the present time i are generally providedwith a centre punch which is operated by means of a brace'device located at the end of the apparatus, the fitting adaptgd to be applied to the valve of the machine being arranged at the side of l the body 'oPthe-bottle. With such an ap-.

paratus it is necessaryjwhen holding 'the bed of the bottle with one hand, to ass the r hand to the other side of the W eel for the pur ose of operating the punch. This operati is extremely awkward and does not permit of holding the fitting pressed efiicien tly upon the valve thus causing a considerable leakage of the air contained in the bottle. The present invention has for its subject an air bottle which can be operated easily and which prevents losses of air. This bottle which constitutes 'anew industrial product, is more particularly characterized bottle, of a closing device screwed upon the latter andof which the operatio'n is effected by holding it with one hand' and turning the bottle slightly with the otherhand, the two hands being placed on the same side in relation to the Wheel. At the outer end of the said closing device thefio is screwed a self-adapting fitting directed at right angles to the axis oi the bottle.

The invention alsohas for-its subject various forms of construction of the new industrial product in question. v

' Figure 1 is a view in elevation of a device which is operated by holding in the hand an external sleeve secured to the closing device. p p Figure 2 is a vertical section corresponding to Figure 1; j Figure 3 is a modification in which the operation is effected by means of a milled head which may be engaged between the thumb and the first finger.

bythe combination. with the body of the Figure 8 shows partly in elevation, partly 1n cross section the same construction. F1gure 9 shows in elevation an external view of a fourth form of construction.

Figure 10 shows in elevation an external view of a fifth form of construction, and

Figure 11 shows a longitudinal section of the last mentioned form .of construction.

As shown in Figures 1 and 2 the app aratus comprises .the bodyl of the bottle of which the upper end isprovided with an external screw thread 2 on which. is screwed a sleeve 3 from which extends an externally threaded sleeve 4. The sleeve 3 is internally threaded so as to receive a tube 5 at the end of which is screwed the self-adapting fitting 6 directedat right angles to the axis of the bottle. In the interlor of the sleeve 3 is disposed a metal disc 7 of whichthecqntral portion is provided witha coni cal projection 8 of which the point is adapted to close the outlet orifice 9 of thQ'bOttlB; Thedisc 7 of which the diameter i-sfslightly less than the internal diameter of the sleeve 3, is provided with a 'diametral groove '10 extending through the whole thickness thereof. A rubber washer 11 forced into the sleeve 3 holds therdisc 7 against the bottom of the sleeve 3. On the extension ear the latter is loosely mounted sleeve 12 which partly covers the body of the bottle and of which the height is sufiiciently large to enable it to be gripped by the hand. A nut '13 which isscrewed on the part 4 enables the sleeve 12 to be secured to the sleeve 3 which latter is also provided with aprojection 14 which is adapted to engage with an opening 15 provided in the upper part of the sleeve 12. o

The operation of lows t 'When it is desired 'to,use the apparatus for inflating the inner tube of a bicycle, the body 1 of the bottle is gripped in the right hand and the self-adapting fitting 6 is pressed against the valve. The sleeve 12 is then gripped by the left hand and the body of the bottle is slightly unscrewed so .as to the device .is as folexpose the passage 9 and allow the air: to.-

pass into the inner tube through the pas-- sages 10 and 5 and the fitting 6. Itwill be seen that the two hands can serve-to hold the self-adapting fittingin position on the valve which avoids any risks of leakage reason of the fact that the sleeve 12 is omitted due to accidental separation of these two parts. As it is not necessary to place the hands on opposite sides of the wheel the cycle may be placed. against a wall and the' wheel can be held against the ground by the foot. As soon as the inner tube has been sufliciently inflated, a slight turning of the body of the bottle brings the point of the cone 8 into the passage 9 and instantly stops the passage of air. A a

The deviceshown in Figures 3 and 4 ditfers from that shown in Figures 1 and 2 by and the sleeve 3 is gripped directly between the thumb and first finger, for which purpose the exterior of the sleeve 3 is milled.

It will be understood-that the invention is not limited to the formsof construction which have been described and these are capable of being modified in detail without varying the scope of the invention by reason of these modifications.

, the end 4 of the body 1.

The upper part 19 of the handle 16 forms a kind of cap in the central portion of which is provided .an opening 20 through which passes the outer .end of a member 21 whose other end 22 slides in the interior of a cylindrical passage 23 provided in the bottom 18 a of the body 1. The outer end .24 of the member 21 is screw threaded and the selfadapting fitting 6 may be screwed thereon.

At the end otth-e internal portion thereof,

7 the said member 21 is provided with a conical extension 8 forming a kind of pointed shell adapt'ed,when it is pressed against the opening 9 provided in the bottomot the body 1,.to close this opening. I Along the axis of the member 21 there is provided a passage 5 which communicates with the exterior adjacent the wall of the shell 8 by auxiliary. passages 25.

On the outer surface of the member 21 there is provided a.circular shoulder 26 .on

which bears the edge 27 of the opening 20 provided in the hood of the handle 16.

Below the lower shoulder 28 of the member 21 and the bottom 18 of the body 1 there is disposed a rubber ring 29 which produces the fluid tightness of the apparatus, during its operation.

A spring 30 locatetl between the iriner surof the body 231 of the apparatus acts upon the handle 1 in such a manner as to cause the poiht of the shell 8 to bear against the opening 9 in the bottom 18 of the body 1.

The operation of the apparatus is very' simple. After the self-adapting fitting 6 has been placed against the valve of the inner tube which is to be inflated it sufiices to press upon the handle 16 asto cause it to approach the body 1 by turning onthe pivot 17.

face of the handle 16 and the. outer surface During this movementtheedge 27 of the v I opening 20 in the hood moves a shoulder 26 of the member 21 and consequently enables this member to move under the action of the compressed-air contained in th body 1.

When the handle 16 isreleas d, the spring 30 tends to turn the handle in the opposite direction about the pivot 17 and consequently returns the shell 8 against the edges of the orifice 9 thus closing the latter. The method of construction shown in Figure 9 is exactly similar in construction to the arrangement-shown in Figure 3 as regards the internal arrangements of the elements. This construction only difiering in the external members, the sleeve-3 with three milled rings is replaced for the convenience of operation, by a member 31 provided with a roughened operating lug 32.

device to be actuated and for closing the bottle is arranged at the lower end of the latter.

The closing member 33 is provided at the end of a.rod 34 of which the part adjacent the member 33 is screw threaded .and may be screwed into a sleeve 35-.formed integral with the bottom of the body 1.

Th rod 34 which extends along the whole lengt of the bottle engages at its lower end 36, which is suitably flattened, with a groove 37 provided centrally in a member 38 of which the end 39 is secured to theoperating sleeve 41 by a nut 40.

The member 38 is also provided with ab shoulder 42 which, in combination with the end of a nut 43 screwed into thebottom 44 i vice. The washer 46 disposed between the front face of the nut 43 and the. bottom 44 of the body ensures the fiui d tightness of the 010- sure.
